Abstract: Nano nitrogen, zinc, and copper treatments significantly influenced attributes such as plant height, number of effective tillers, panicle length, and the number of grains per panicle compared to the control. The results showed that treatment T8 (100% PK + 50% N + 2 sprays of nano N @ 4 ml per liter of water + Cu @2 ml per liter of water + Zn @ 2 ml per liter of water at 25 & 50 DAS) produced the highest grain yield (2020.74 Kg ha-1), significantly outperforming other treatments. This was followed by treatment T6 (100% PK + 50% N + 2 sprays of nano N @ 4 ml per liter of water + Zn @ 2 ml per liter of water at 25 & 50 DAS) with a yield of (1800.74 Kg ha-1), which was at par with treatment T7 (100% PK + 50% N + 2 sprays of nano N @ 4 ml per liter of water + Cu @ 2 ml per liter of water at 25 & 50 DAS) yielding (1794.41 Kg ha-1). These treatments were closely followed by T5, T3, and T4. Treatment T8 also resulted in the tallest plant height (117.38 cm), the highest number of effective tillers (373.28 m-2), the longest panicles (10.50 cm), and the greatest number of grains per panicle (1267.23). Additionally, T8 had the highest B:Cratio (2.76:1) and net profit (52265.57 Rs ha-1).
